See full text

A method for the preparation of functionalized particles includes providing a feedstock that includes particles, a surface treatment agent reactive with the particles and solvent. The feedstock is direct through a continuous hydrothermal reactor maintained at a temperature sufficient to react the particles with the surface treatment agents to thereby provide functionalized particles. The method of the invention is capable of providing the functionalized particles in less than about 4 hours.
